DC To DC Converter circuit used to be an convert voltage DC to DC with different concepts. DC to DC converter circuit +12 V to + /-20V is working to change the battery voltage from 12V DC to 20V DC voltage symmetrical. DC to DC converter circuit is often applied to the power amplifier udio on car audio systems. DC to DC converter circuit uses a TL494 IC as power plsa for the converter.

TL494 IC is a PWM controller with an adjustable frequency from 40-60Hz through a potentiometer. Then from the TL494 PWM signal is given to the driver MOSFET inverter TPS2811P to be given to the power inverter with 2 units of MOSFET transistors. Circuit details can be seen in the figure following the DC to DC converter.
